00013 - Mathematical Analysis

Learning outcomes

The student must develop three types of skills: 1) making computations relative to functions of one or more variables (limits, derivatives, integrals) and being able to solve some problems with the techniques of mathematical analysis (calculate the length of a curve, of a volume or solve some ordinary differential equations);  2) understanding and being able to use the basic definitions of mathematical analysis;3) knowing the elementary functions.

Course contents

Introduction. Basics on set theory, cartesian product, relations. Functions: definition, injective, surjective and bijective functions, composition between functions.

Teaching methods

The course will consist of both theoretical lectures and problem sessions with the aim of making the students familiar with the main concepts and techniques of the course. Moreover, some exercices will be given to the students as homework.

Assessment methods

The exam is a written exam containing  two parts: one of them consists in the resolution of exercises, the other concerns the theoretical aspects of the course, such as deifinitons and theorems.

Teaching tools

The suggested Textbooks and other material that will be available online on the webpage of the teacher.
